I've taken mine on an airplane a few of times, and one time they switched our original plane to a smaller one (after I had called and verified everything ahead of time!) and then they tried to tell me it wouldn't fit in the overheads and they wanted to put it in the cargo hold. Ummm...not a snowball's chance! They ended up putting it up with the stewards.
I haven't had any issues with the other carriers I've flown, they just "bomb sniff" it and open it at security. My bag doesn't have wheels, so I bought a small set of $15 luggage wheels for mine. I can put my suitcase on top of it, and a carseat (turned upsidedown). That made 3 people (2 adults, one toddler) going through the airport with 2 carryons, the vest, a carseat and a stroller much easier! <img src="i/expressions/face-icon-small-smile.gif" border="0">
I have had to tell a securtiy person that that bag she was so roughly handling was a $16,000 piece of medical equipment too!
